experienced The Doppler Effect. The Doppler Effect is defined by the Encarta dictionary as‚ “Change in frequency because of motion: a perceived change in the frequency of a wave as the distance between the source and the observer changes. For example‚ the sound of a siren on a moving vehicle appears to change as it approaches and passes an observer.” (Dictionary‚ 2009) Named after Austrian physicist and mathematician Christian Johann Doppler‚ our book defines the Doppler Effect as a change in

The destructive effects of an earthquake can be classified into primary and secondary effects. Primary effects are the immediate damage caused by the quake‚ such as collapsing buildings‚ roads and bridges‚ which may kill many people. Those lucky enough to survive can suffer badly from shock and panic. Secondary effects are the after-effects of the earthquake‚ such as fires‚ tidal waves‚ landslides and disease. Fire - earthquakes destroy gas pipes and electric cables‚ causing fires to spread

Doppler Effect Objectives * Measure the detector frequency for waves emitted from a slowly moving source as that source is approaching the detector. (Exploration 1) * Calculate the detector frequency for waves emitted from a slowly moving source as that source is moving away from the detector. (Exploration 2) * Sketch the wave-front patterns for wave sources with various source speeds. (Exploration 3) Description of Activity In this activity‚ you will study waves that travel from

GREENHOUSE EFFECTS IntroductionThe greenhouse effect is a process by which thermal radiation from a planetary surface is absorbed by atmospheric greenhouse gases‚ and is re-radiated in all directions. Since part of this re-radiation is back towards the surface and the lower atmosphere‚ it results in an elevation of the average surface temperature above what it would be in the absence of the gases.[1][2] Solar radiation at the frequencies of visible light largely passes through the atmosphere to

Effects of earthquakes Shaking and ground rupture Shaking and ground rupture are the main effects created by earthquakes‚ principally resulting in more or less severe damage to buildings and other rigid structures. The severity of the local effects depends on the complex combination of the earthquake magnitude‚ the distance from the epicenter‚ and the local geological and geomorphological conditions‚ which may amplify or reduce wave propagation.[44] The ground-shaking is measured by ground acceleration

Danielle Mowder Erica Towe English 11 March 9‚ 2015 The Greenhouse Effect Without the greenhouse effect the temperature of this planet would decrease by at least 30 degrees celsius‚ and it would be too cold for us to survive. The light we receive from the sun keeps our atmosphere warm. The earth only absorbs 30% of the sunlight because the other 70% is reflected back into space‚ and is absorbed by greenhouse gases. These gases act like a mirror‚ and reflect heat back to earth. The major greenhouse gases are carbon dioxide

Climate Change When processing the original (virgin) material‚ the amount of energy expended in their extraction as well as transportation usually involve burning fuels which sources of greenhouse gas emissions. Although production of goods through recycling requires use of energy as well‚ the amount

Greenhouse Effect When one starts a car or burns wood‚ the last thought on their mind is the consequences to these actions. Unfortunately‚ the daily dangers to earth are not widely know. Due to the constant change of society‚ this planet must cope with various problems. One of the most important ecological structures is the ozone layer. The same shield that protects us from the sun ’s deadly radiation‚ can also act as a blanket engulfing us in heat. This situation is know as the greenhouse effect. What

Colour of Light Effects on Plant Growth Introduction Photosynthesis is the process of converting light energy to chemical energy and storing it in the bonds of sugar. Plants need water‚ Co2 and light energy to create sugar. Photosynthesis occurs mainly in leaves and in 2 phases: light reaction and dark reaction. The light reactions converts light energy to chemical (Biology.clc.uc.edu‚ 2014). This chemical reaction must take place in the thylakoid membrane. Chlorophyll (the green pigment involved
